I bought the Sony Ericson W380 in January and I have to admit that it has grown on me! I have had a few technical problems with it, but other than that it serves it's purpose.
The way the phone quickly flips open, also gives it a more sexy and slick feel.
The touch sensative screen is meant to give you the ability to gesture for calls to be blocked, but i have never managed to be able to do this. It's also meant to let you control your music but I have found this difficult to master too. However this might be because I'm not that good at technical things and I most likely didn't read the instructions properly.
One of the other downsides is that I find it to be a bit bulky. Also the internet and camera are of poor quality. In fact, Every picture I have taken has been unclear and I haven't been able to use any of them.
